NR1 is an intege
r that specifies the number of events to run. The default
is 1 event and the maximum is 1000000 events. A repeat count greater
than 1000000 specifies to run forever. In this case, the action on event can be
terminated by setting the state for all actions to OFF. When the repeat count is set
to infinite, the query returns 9.9E+37 (IEEE positive infinity).
AFG:AMPLitude
Sets (or qu
eries) the AFG amplitude in volts, peak to peak. The minimum and
maximum allowable settings are dependent upon the output load impedance setting
(AFG:OUTPut:LOAd:IMPEDance) and the selected function (AFG:FUNCtion).
NOTE. The AFG:OUTPut:LOAd:IMPEDance command must be used before
using any of the amplitude/offset/highLevel/lowLevel/Preset commands, so that
saved setups are recalled with the proper load factor applied.
The following values can be set for AFG:AMPLitud e:

The DC function does not use the amplitude setting. The DC level is set using :AFG:OFFSet. Ampltude settings that are set when the :AFG:FUNCtion is DC
are remembered and applied when the function is changed to other than DC.

Syntax
AFG:AMPLitude <NR3>
AFG:AMPLitude?
Arguments
Floating point number that represents the AFG amplitude, peak to peak, in volts.
Examples
AFG:AMPLITUDE 1.0 sets the AFG amplitude to 1.0 volts, peak to peak.
AFG:ARBitrary:ARB<x>:DATE? (Query Only)
Returns the date that the data in the specified arbitrary waveform slot 1-4 was
saved.
Conditions
MDO3000 series with option MDO3AFG installed and MDO4000C series with
option MDO4AFG installed only.
Group
ARB
Syntax
AFG:ARBitrary:ARB<x>:DATE?
Examples
AFG:ARB:ARB3:DATE? might return 11-11-13, which represents the date that
thedatainslot3wassaved.
AFG:ARBitrary:ARB<x>:LABel
Sets (or queries) the waveform label for arbitrary waveform slots 1- 4.
Conditions

:ARB<x>:LABel <QString>
AFG:ARBitrary:ARB<x>:LABel?
Arguments
Quoted string that represents the waveform label for one of the arbitrary waveform
slots 1-4.
Examples
AFG:ARBITRARY:ARB4 “Foo” sets the waveform label for arbitrary waveform
slot4to“Foo.”
AFG:ARBitrary:ARB<x>:TIMe? (Query Only)
Returns the time that the data in the specified arbitrary waveform slot was saved.
Conditions
MDO3000 series with option MDO3AFG installed and MDO4000C series with
option MDO4AFG installed only.
Group
ARB
Syntax
AFG:ARBitrary:ARB<x>:TIMe?
Examples
AFG:ARB:ARB3:TIME? might return "14:43:29", which represents the time
that the data in the slot 3 was saved.
AFG:ARBitrary:EMEM:FUNCtion? (Query Only)
Returns the currently selected arbitrary waveform pre-defined function.
The pre-defined ARB function is selected using the command
AFG:ARBitrary:EMEM:GENerate.
This query may also return
USER, which indicates that the arbitrary waveform in
edit memory has been altered from one of the predefined functions.
Conditions
